Applications

The RFM300 is a powerful
solution for monitoring ATSC transmitter sites and off-air monitoring,
as well as contribution and distribution monitoring at local and national
operation centers and headends

RFM300
Delivers Comprehensive DTV Monitoring

The RFM300 provides
a complete solution for real-time DTV monitoring of MPEG transport
streams. The comprehensive RF and PSIP confidence-monitoring capability
provides a powerful and cost-effective solution for monitoring DTV
transmitter sites, along with contribution and distribution feeds
at local and national operation centers for FCC compliance.

The RFM300 delivers comprehensive RF 8VSB measurements which include
symbol distribution waterfall chart, MER and PSIP analysis (includes
an Electronic Program Guide). This can be combined with a single diagnostic
option to provide enhanced diagnostic capability that includes detailed
service logging, in-depth PCR analysis, triggered recording and template
testing. The extended confidence-monitoring probes can be installed
throughout the network and powerful diagnostic capability can be added
to the key monitoring points where transport streams are manipulated.

When used together with VQNet™, facility and network-wide views
allow engineers to sectionalize network problems.

*2 Maximum transport stream bit rate is
dependent on transport stream content and depth of analysis being
performed. Depth of stream analysis is handled gracefully if SI/PSIP
max content is exceeded to ensure critical measurements continue to
be performed.
